WATCH BELOW: The latest on Prince Louis

The 11-week-old prince, who was born Louis Arthur Charles on April 23, was christened by the Archbishop of Canterbury, Justin Welby. His Royal Highness Prince Louis of Cambridge is fifth in line to the throne, and the sixth great-grandchild of Queen Elizabeth.

The Queen and her husband, the Duke of Edinburgh, didn’t attend the christening, but it was a decision made “some time ago” and wasn’t due to health reasons.
